Definitions

  • the present invention relates to a packaging laminate for a retortable packaging container comprising a core layer, outer, liquid-tight coatings and an aluminium foil between the core layer and the one outer coating and serving as a gas barrier.
  • a packaging laminate of the type which is described above is known from, for example, international patent application carrying publication number WO97/02140 .
  • the prior art packaging laminate has a rigid, but foldable core layer of paper or paperboard and outer, liquid-tight coatings of moisture and heat resistant plastic material on both sides of the core layer.
  • the packaging laminate In order to impart to the prior art packaging laminate tightness properties also against gases, in particular oxygen gas, the packaging laminate moreover displays an aluminium foil which serves as gas barrier and which is disposed between the paper or paperboard layer and the one outer plastic coating.
  • retortable packaging containers are produced with the aid of filling machines of the type which, from a web or from prefabricated blanks of the packaging laminate, form fill and seal finished packages in accordance with the so-called form/fill/seal principle well-known in packaging contexts.
  • retortable packaging containers are produced in that the packaging blank is first raised to an open, tubular packaging carton which is sealed at its one end by fold forming and thermosealing of continuous, foldable end panels of the packaging carton, for the formation of a substantially planar bottom closure.
  • the packaging carton provided with a bottom is filled with the relevant contents, e.g. food, through its open end which is thereafter sealed by an additional fold forming and thermosealing of corresponding end panels of the packaging carton for the formation of a substantially planar top closure.
  • the filled and sealed, normally parallelepipedic packaging container is thereafter ready for a heat treatment in order to impart to the packed contents or food extended shelf-life in its unopened packaging container.
  • a heat treatment which extends shelf-life may suitably be carried into effect in the manner and under the conditions described in international patent application carrying publication number WO98/16431 .
  • the packaging container is, in this instance, placed in a retort and is heated therein with the aid of a first gaseous medium flowing in contact with the outer walls of the packaging container, e.g. hot steam, to a temperature generally within the range of 70-130°C. After a predetermined stay time at the selected temperature, the supply of the gaseous medium is discontinued.
  • the packaging container is cooled with a second, circulating gaseous medium, e.g. cold air, and finally with a circulating liquid medium, e.g. cold water.
  • the cooled, retorted packaging container is thereafter removed from the retort for storage, transport and/or other handling.
  • US 3972467 describes a laminate containing a layer of high strength polymer film and an Al barrier layer
  • One object of the present invention is, therefore, to obviate the above-described drawback in connection with the prior art packaging laminate.
  • a further object of the present invention is to provide a packaging laminate of the type described by way of introduction which may readily be reformed by fold forming and thermosealing into a retortable packaging container without the risk that the packaging container loses its desirable tightness properties against gases, in particular oxygen gas, even if the tensile-sensitive aluminium foil is subjected to crack formation and similar untightness during fold forming of the packaging laminate.
  • Yet a further object of the present invention is to provide a retortable packaging container produced from the packaging laminate for perishable and oxygen gas-sensitive food products.
  • the present invention provides a packaging laminate for a retortable packaging container, the packaging laminate (30) including a rigid but foldable core layer (31) of paper or paperboard, outer liquid-tight coatings (32,33), an aluminium foil (34) serving as gas barrier and disposed between the core layer (31) and the one outer liquid-tight coating (32), and at least an additional layer (35) serving as a gas barrier between the core layer (31) and the aluminium foil (34), said at least one additional layer (35) being bonded to the core layer (31) by an interjacent lamination or adhesive layer (36), wherein the outer layer (32) on the side of the core layer (31) bearing the aluminium barrier layer (31) is of a copolymer of propylene and ethylene having sufficient moisture and heat resistance to withstand the heat treatment, the outer layer (33) on the side of the core layer (31) away from the aluminium barrier layer (34) is of a physical mixture of polypropylene and polyethylene having sufficient moisture and heat resistance to withstand the heat treatment, and the interjacent lamination or adhesive
  • the present invention also provides a retortable packaging container for particularly perishable and oxygen gas-sensitive products produced by fold forming and sealing of the packaging laminate according to the present invention.
  • the invention includes a method of extending the shelf life of a product packed in a container produced by fold forming and thermosealing of a packaging laminate (20, 30) which includes a rigid but foldable core layer (21, 31) of paper or paperboard, outer liquid-tight coatings (22,32; 23,33), an aluminium foil (24, 34) serving as gas barrier and disposed between the core layer (21, 31) and the one outer liquid-tight coating (22, 32), and at least an additional layer (25, 35) between the core layer (21, 31) and the aluminium foil (24, 34), said at least one additional layer (25, 35) serving as a gas barrier between the core layer and the aluminium foil, wherein the outer layer (32) on the side of the core layer (31) bearing the aluminium barrier layer (31) is of a copolymer of propylene and ethylene having sufficient moisture and heat resistance to withstand the heat treatment, the outer layer (33) on the side of the core layer (31) away from the aluminium barrier layer (34) is of a physical mixture
  • Fig. 1 shows the general structure of a prior art packaging laminate carrying the generic reference numeral 10.
  • the packaging laminate 10 has a rigid, but foldable core layer 11 of paper or paperboard, as well as outer, liquid-tight coatings 12 and 13 on both sides of the core layer 11.
  • the packaging laminate 10 further displays an aluminium foil 14 serving as gas barrier and disposed between the core layer 11 and the one outer, liquid-tight coating 12.
  • a retortable packaging container is produced in a per se known manner by fold forming and thermosealing of a sheet- or web-shaped blank of the packaging laminate 10.
  • a flat-folded tubular packaging blank such a retortable packaging container is produced in that the packaging laminate is first raised to an open, tubular packaging carton whose one end is sealed by fold forming and thermosealing of continuous, foldable end panels of the packaging carton for the formation of a substantially planar bottom closure.
  • the packaging carton with the closed bottom is filled with the relevant contents, e.g.
  • a food through its open end and is thereafter given a substantially planar top closure by additional fold forming and thermosealing of corresponding continuous, foldable end panels of the packaging carton.
  • the thus filled and closed, normally parallelepipedic packaging container is thereafter ready for a heat treatment in a retort in order to impart to the packed contents or food so-called extended shelf-life in the unopened packaging container.
  • the problem inherent in the prior art packaging laminate 10 is, as has already been described, that the aluminium foil 14 included in the packaging laminate can, because of its tensile sensitivity, crack, in particular in areas where tensile stresses on the aluminium foil are particularly powerful during the reforming of the packaging laminate into a packaging container, and that the produced packaging container thereby loses tightness properties against gases.
  • Such cracks and similar untightness in the aluminium foil of the packaging laminate can, in certain cases, be so extensive and serious that the packaging container becomes totally unusable, in particular if the packaging container is intended to be used for particularly perishable and oxygen gas-sensitive foods which would rapidly be destroyed and deteriorate in quality if they came into contact with oxygen gas.
  • the prior art packaging laminate may be modified to provide a packaging laminate (not according to the present invention) with a structure illustrated schematically in Fig. 2 .
  • the packaging laminate carrying the generic reference numeral 20 in Fig. 2 similarly displays a rigid, but foldable core layer 21 of paper or paperboard and outer, liquid-tight coatings 22 and 23. Between the core layer 21 and the one outer, liquid-tight coating 22, the packaging laminate 20 has an aluminium foil 24 serving as gas barrier.
  • the packaging laminate 20 according to the present invention differs from the prior art packaging laminate 10 in Fig. 1 principally in that it displays, between the aluminium foil 24 and the core layer 21, an additional layer 25 serving as gas barrier in order to compensate for or counteract possible cracks which may occur in the aluminium foil 24 when the packaging laminate 20 is reformed into a packaging container.
  • Preferred materials for the additional or supplementary gas barrier layer 25 in the packaging laminate 20 according to the present invention may be selected from the group essentially comprising polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), cyclic olefin copolymers (COC), polyamide (PA), amorphous polyamide (APA), liquid crystalline polymers (LCP), ethylene vinyl alcohol copolymers (EVOH) and polyvinyl alcohol (PVOH) which may possibly be applied on a thin carrier layer, such as, for example, paper.

  • APA amorphous polyamide
  • LCP liquid crystalline polymers
  • EVOH ethylene vinyl alcohol copolymers
  • PVOH polyvinyl alcohol
  • the liquid-tight coating 23 consists of a physical mixture of polypropylene (PP) and polyethylene (PE) which, in addition to superior tightness properties against liquid, also has sufficient moisture and heat resistance to withstand such extreme moisture and temperature stresses as occur in a normal heat treatment in a retort for extending shelf-life.
  • An outer coating 23 of a physical or mechanical mixture of polypropylene (PP) and polyethylene (PE) moreover displays superior printability, at the same time as making for mechanically strong and liquid-tight seals by thermosealing when the packaging laminate 20 is reformed into retortable packaging containers.
  • the thickness or quantity of the outer, liquid-tight coating 23 may vary within broad limits, but is generally 25-45 g/m 2 .
  • the liquid-tight coating 22 consists of a copolymer of propylene and ethylene which is sufficiently moisture and heat-resistant to withstand extreme moisture and temperature stresses which occur in a normal heat treatment in a retort intended to extend shelf-life.
  • a coating of a copolymer of propylene and ethylene moreover makes for mechanically strong and liquid-tight seals when the packaging laminate 20 is reformed into a packaging container for retorting purposes.
  • the thickness or quantity of the outer plastic coating 22 may vary within broad limits, but is generally within the range of 25-35 g/m 2 .
  • the layer 25 employed as an additional gas barrier between the core layer 21 and the aluminium foil 24 in the packaging laminate 20 according to the present invention.
  • the quantity or thickness of the layer 25 in the illustrated embodiment is in general 10-30 g/m 2 .
  • Fig. 3 schematically illustrates a packaging laminate 30 according to one preferred embodiment of the present invention.
  • the packaging laminate 30 includes a rigid, but foldable core layer 31 of paper or paperboard and outer, liquid-tight coatings 32 and 33. Between the core layer 31 and one of the two outer, liquid-tight coatings 32, the packaging laminate 30 has an aluminium foil 34 serving as gas barrier.
  • the packaging laminate 30 differs from the prior art packaging laminate 10 in Fig. 1 in the same manner as the packaging laminate 20 in Fig. 2 principally in that, between the aluminium foil 34 and the core layer 31, it has an additional layer 35 serving as gas barrier to compensate for or counteract possible cracks which may occur in the aluminium foil 34 when the packaging laminate 30 is reformed into a packaging container.
  • Preferred materials for the additional or supplementary gas barrier layer 35 in the packaging laminate 30 may be selected from the group essentially comprising polyethylene terephthalate (PET), amorphous polyethylene terephthalate (APET), cyclic olefin copolymers (COC), polyamide (PA), amorphous polyamide (APA), liquid crystalline polymers (LCP), ethylene vinyl alcohol copolymers (EVOH) and polyvinyl alcohol (PVOH) which may optionally be applied on a thin carrier layer, such as, for example, paper.

  • APET amorphous polyethylene terephthalate
  • COC cyclic olefin copolymers
  • PA polyamide
  • APA amorphous polyamide
  • LCP liquid crystalline polymers
  • EVOH ethylene vinyl alcohol copolymers
  • PVOH polyvinyl alcohol
  • the liquid-tight coating 33 consists of a physical mixture of polypropylene (PP) and polyethylene (PE) which, in addition to superior tightness properties vis-à-vis liquid, also displays sufficient moisture and heat-resistance to withstand such extreme moisture and temperature stresses as occur in a normal heat treatment in a retort for extending shelf-life.
  • An additional coating 33 of a physical mixture of polypropylene (PP) and polyethylene (PE) moreover displays superior printability, at the same time as it makes for mechanically strong and liquid-tight seals by thermosealing when the packaging laminate 33 is reformed into retortable packaging containers.
  • the thickness or quantity of the outer liquid-tight coating 33 may vary within broad limits, but is in general within the range of 25-45 g/m 2 .
  • the liquid-tight coating 32 consists of a copolymer of propylene and ethylene which is sufficiently moisture and heat-resistant to withstand extreme moisture and temperature stresses which occur in a normal heat treatment for extending shelf-life which is carried out in a retort.
  • a coating of a copolymer of propylene and ethylene moreover makes for mechanically strong and liquid-tight seals when the packaging laminate 30 is reformed into a packaging container for retorting purposes.
  • the thickness or quantity of the outer plastic coating 32 may vary within broad limits, but is in general within the range of 25-35 g/m 2 .
  • the layer 35 used as additional gas barrier is bonded to the core layer 31 by at least one interjacent lamination or adhesive layer 36.
  • the interjacent lamination or adhesive layer 36 By a suitable selection of material in the interjacent lamination or adhesive layer 36, among others the advantage will be gained in comparison with the packaging laminate 20 in Fig. 2 that the quantity or thickness of the layer 35 employed as additional gas barrier may be made thinner without the tightness properties of the packaging laminate 30 being negatively affected.
  • the material in the layer 36 is polypropylene (PP) with which the thickness of the additional gas barrier layer 35 may be made as thin as 5-20 g/m 2 with gas tightness properties of substantially the same order of magnitude as the packaging laminate 20 in Fig. 2 which does not employ such an interjacent layer of polypropylene or other olefin polymer.
  • the packaging laminate 30 according to the preferred embodiment of the present invention illustrated in Fig. 3 is thus a more economical, but just as efficient packaging laminate as the packaging laminate 20 for a retortable packaging container which is intended principally for particularly perishable and oxygen gas-sensitive products such as foods.
  • the present invention by merely a simple modification of the prior art packaging laminate, provides a packaging laminate which, by fold forming and sealing, may be reformed into a retortable packaging container possessing sufficiently good tightness properties against gases, in particular oxygen gas, in order reliably to be able to store particularly perishable and oxygen gas-sensitive products such as foods.
